  • the other end of the recoil rope 2, one end of which is pulled out to the outside of the starter housing 1, is fixed to the rope reel 4 and wound around the rope reel 4.
  • the rotational force of the cam 8 in the engine starting direction is transmitted to the crankshaft of the engine via the drive pulley 9 by engaging the cam pawls 11 with the centrifugal ratchet 10 of the drive pulley 9.
  • the drive pulley 9 is rotated by the engine, whereby the centrifugal ratchet 10 is rotated by centrifugal force in the direction in which the cam pawls 11 disengage, so that transmission of the rotational force between the engine and the cam 8 is blocked.
  • the rope reel 4 and the cam 8 are disposed so that their side surfaces face each other, and annular recesses 12 and 13 are respectively formed in the opposing side surfaces of the rope reel 4 and the cam 8 in such a manner that the annular recesses 12 and 13 face each other.

  • the damper spring 14 is formed in the shape of a torsion coil spring and provided at one end thereof with an engaging end portion 15 which is formed by bending the end portion into a U-shape in a horizontal direction.
  • the engaging end portion 15 is received in a holding groove 16 formed continuously with the outer periphery of the annular recess 12 formed in the rope reel 4, so that the rope reel 4 and the damper spring 14 are rotatingly connected to each other.

  • the damper spring 14 is resiliently received in the annular recess 12 in a state where the damper spring 14 comes into tight contact with the outer side peripheral wall 19 of the annular recess 12.
  • the cam pawl 11 of the cam 8 engages with the centrifugal ratchet 10, so that the drive pulley 9 is rotated via the centrifugal ratchet 10, resulting in the crankshaft of the engine joined to the drive pulley 9 being rotated.
  • the handle damper 25 is compressed to absorb the shock of the load fluctuations propagated to the operating handle 3 via the recoil rope 2, and, at the same time, the pulling force of the recoil rope 2 is accumulated in the damper handle 25.
  • the engine has not started by one starting operation, and when the recoil rope 2 is returned in order to try starting the engine again, the cam 8 is rotated in the opposite direction via the damper spring 14 integrally with the rope reel 4.

  • the damper spring 14 is resiliently received in the annular recesses 12 and 13 while the damper spring 14 is kept in tight contact with the peripheral wall 19 of the annular recess 12 formed in the rope reel 4, after the engine has been started, relative vibrations between the damper spring 14 and the rope reel 4 or cam 8 are not generated, and even when vibrations at the time the engine is running are propagated to the recoil starter, abrasion of engaging portions of the holding groove 16 and the holding hole 18 resulting from vibrations of the damper spring 14 can be prevented. Therefore, sufficient durability can be exhibited even if parts such as the rope reel 4 and the cam 8 are formed of a plastic material.

  • the diameter of the outer side peripheral wall 20 of the annular recess 13 formed in the cam 8 is formed so as to be smaller than the diameter of the peripheral wall 19 of the outer side of the annular recess 12 of the rope reel 4, whereby the damper spring 14 is received in the annular recesses 12 and 13 while the damper spring 14 comes into tight contact with the peripheral wall 20 of the annular recess 13 of the cam 8.
  • Fig. 7 shows yet another modified example of the recoil starter according to the above-described embodiment.
  • the free length of the damper spring 14 is set to be larger than the distance between bottom surfaces 12a and 13a of the annular recesses 12 and 13 formed in the rope reel 4 and the cam 8, and the damper spring 14 is received in the annular recesses 12 and 13 in a state where it is compressed between the bottom surfaces 12a and 13a.
  • vibrations of the damper spring 14 due to the rotation of the engine can be effectively prevented, so that it is possible to prevent abrasion of the engaging portions of the rope reel 4 and the cam 8.
  • a recoil starter according to another embodiment of the invention shown in Figs. 8 to 14 will be described below. Because the basic configuration of the recoil starter of this embodiment is the same as that of the aforementioned embodiment, a detailed description thereof will be omitted by giving reference numerals that are the same as those of the aforementioned embodiment to the same parts in the drawings.
  • the damper spring 14 is arranged between the rope reel 4 and the cam 8 in a state where an initial load of a torsional direction is applied in advance to the damper spring 14 in order to prevent abrasion of parts resulting from vibrations of the damper spring 14.
  • a rotation regulating means 30 for regulating the amount of a relative rotation between the rope reel 4 and the cam 8 is provided in order to maintain the initial load of the damper spring 14 and in order to prevent a reduction in durability of the damper spring 14 resulting from excessive distortion and constriction of the damper spring 14.
  • the damper spring 14 is received in the annular recesses 12 and 13 formed in mutually facing side surfaces of the rope reel 4 and the cam 8.

  • the plurality of holding holes 18 are formed at substantially equal intervals along the circumference of the annular recess 13 of the cam 8, so that the engaging end portion 17 of the damper spring 14 can be selectively inserted into any one of the holding holes 18.
  • the rotation regulating means 30 for regulating the relative rotation between the rope reel 4 and the cam 8 is arranged between the rope reel 4 and the cam 8.
  • the rotation regulating means 30 is constituted by a first stopper piece 31, which is formed on the side surface of the rope reel 4 facing the cam 8 so as to protrude from the outside of the annular recess 12 formed in the side surface of the rope reel 4, and a second stopper piece 34, which is formed on an outer peripheral surface of the cam 8 adjacent to the side surface of the cam 8 facing the rope reel 4 so as to protrude radially outward, so that the second stopper piece 34 faces the first stopper piece 31 of the rope reel 4.
  • the rotation regulating means 30 is set so that, when the relative rotation angle of the rope reel 4 with respect to the cam 8 has become about 300 degrees or more, the front end surface 32 of the first stopper piece 31 and the rear end surface 35 of the second stopper piece 34 are brought into contact and the relative rotation between the rope reel 4 and the cam 8 is restricted.
  • the damper spring 14 is disposed between the rope reel 4 and the cam 8 in a state where the initial load in the engine starting rotation direction has been applied to the damper spring 14 in advance. For this reason, the cam 8 is rotatingly urged, with respect to the rope reel 4, in the engine starting rotation direction in a state where the rope reel 4 and the cam 8 are joined to each other via the damper spring 14.
  • the end of the recoil rope 2 wound around the rope reel 4 is inserted into the through hole 24 formed in the operating handle 3 and is held on an end portion of the collar 26 that is disposed to be in contact with the end portion of the handle damper 25 constituted by a compression coil spring disposed in the interior of the through hole 24.
  • the recoil rope 2 is pulled out via the handle damper 25 by pulling the operating handle 3.
  • the load of the damper spring 14 when the rope reel 4 relatively rotates about 300 degrees with respect to the cam 8 and the rotation is restricted by the rotation regulating means 30 is set to become slightly smaller than the starting torque of an average engine.
  • the damper spring 14 is twisted about 300 degrees so that a sufficient rotational force is accumulated in the damper spring 14, and when the engine is to be started, this rotational force is effectively transmitted to the cam 8 so that it can become easy to start the engine.
  • the load of the handle damper 25 is set so that a maximum load becomes larger than the starting torque load of the engine, whereby shock due to fluctuations of the load of the engine, when a large load exceeding the starting torque of an average engine is generated and the rotation between the rope reel 4 and the cam 8 is restricted by the rotation regulating means 30, can be effectively absorbed by the handle damper 25.
  • the positions at which the first stopper piece 31 and the second stopper piece 34 are disposed are set so that both stopper pieces 31 and 34 are brought into contact with each other before the outer diameter of the damper spring 14 is reduced by the torsional distortion or deformation of the damper spring 14 and the damper spring 14 constricts the peripheral wall surfaces of the inner peripheral side of the annular recesses 12 and 13 of the rope reel 4 and the cam 8. Thus, constriction of the damper spring 14 is prevented. Additionally, the damper spring 14 is distorted to its maximum distortion angle and the rotational force for starting the engine is effectively accumulated.
  • the handle damper 25 received inside the operating handle 3 is also deformed in accordance with the increase of the load torque of the engine, since the handle damper 25 is set to a load that is larger than the damper spring 14, the first stopper piece 31 and the second stopper piece 34 of the rotation regulating means 30 engage as described above, whereby even after the rope reel 4 and the cam 8 are integrally connected and rotate, as shown in Fig. 14, the buffer effect is exhibited between the recoil rope 2 and the operating handle 3, shock transmitted to the operating handle 3 via the rope reel 4 and the recoil rope 2 due to fluctuations of the load of the engine is buffered, and the shock is not transmitted to the operating handle 3. Moreover, the pulling force of the operating handle 3 is accumulated in the handle damper 25 due to the handle damper 25 being compressed by pulling the operating handle 3.
  • the annular recesses are formed in the joint surfaces of the cam and the rope reel, and the damper spring of the torsion coil shape is received in the recesses in a state where the damper spring is distorted to reduce the diameter thereof and comes into tight contact with the peripheral wall of one of the annular recesses, or in a state where the damper spring is compressed between the bottom surfaces of the recesses, so that the damper spring does not vibrate inside the annular recesses due to vibrations of the engine or the like after the engine has started, abrasion of portions of the holding groove and the holding hole of the rope reel and the cam formed of a plastic material can be prevented, a deterioration in functions at the time of the starting operation due to a play resulting from abrasion can be prevented, and the durability of the recoil starter can be improved.
  • the rotation restricting means for restricting the maximum distortion angle of the damper spring is arranged between the rope reel and the cam, so that the relative rotation angle between the rope reel and the cam is restricted by the rotation restricting means before the amount of the torsional distortion of the damper spring becomes so large that the outer diameter of the damper spring is reduced to make the damper spring constrict the peripheral walls of the rope reel and the cam, whereby the phenomenon in which the damper spring constricts the peripheral walls of the rope reel and the cam does not occur.
  • the rotation restricting means prevents the damper spring from being distorted to an excessive distortion angle, the damper spring with a lengthened life span undergoes repeated distortions, resulting in the durability of the recoil starter being improved.
  • the damper spring is held on the rope reel and cam while an initial load in an engine starting rotational direction is applied to the damper spring, and a rotation restraining means is arranged between the rope reel and the cam to restrain rotation of the cam relative to the rope reel in an engine starting rotational direction, so that relative vibrations do not occur between the damper spring and the rope reel or the cam. Therefore, abrasion of the portions of the holding groove and the holding hole resulting from vibrations of the damper spring can be prevented, whereby a sufficient durability of parts, such as the rope reel and the cam, is obtained even when the parts are formed of a plastic material.
  • the damper spring is interposed between the rope reel and the cam, and a handle damper is provided within the operating handle in such a manner that the end of the recoil rope wound on the rope reel and drawn out from the starter housing is mounted to the operating handle through the handle damper, so that shock due to fluctuations of load is absorbed by the handle damper even after the action of shock absorption between the rope reel and the cam has been lost due to constriction of the damper spring or due to the rotation restricting means in a state where the damper spring disposed between the rope reel and the cam has been maximally distorted.
  • shock of the operating handle pulling the recoil rope is buffered, resulting in the starting operation of the engine being conducted easily.
  • the elastic force accumulated by the deformation of the handle damper is also transmitted as a rotational force to the cam via the rope reel, the engine can be started more easily.
